md5帮助类 
、引入库

using System.Security.Cryptography;//引用Md5转换功能

、计算字符串的Md5值 

        public static string GetMD5WithString(String input)
        {
            MD5 md5Hash = MD5.Create();
            // 将输入字符串转换为字节数组并计算哈希数据
            byte[] data = md5Hash.ComputeHash(Encoding.UTF8.GetBytes(input));
            // 创建一个 Stringbuilder 来收集字节并创建字符串
            StringBuilder str = new StringBuilder();
            // 循环遍历哈希数据的每一个字节并格式化为十六进制字符串
            ; i < data.Length; i++)
            {
                str.Append(data[i].ToString("x2"));//加密结果"x2"结果为32位,"x3"结果为48位,"x4"结果为64位
            }
            // 返回十六进制字符串
            return str.ToString();
        } 

、计算文件的Md5值
         static public string GetMD5WithFilePath(string filePath)
         {
             FileStream file = new FileStream(filePath, FileMode.Open, FileAccess.Read, FileShare.Read);
             MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();
             byte[] hash_byte = md5.ComputeHash(file);
             string str = System.BitConverter.ToString(hash_byte);
             str = str.Replace("-", "");
             return str;
         }

文件和文本的MD5

            catch (Exception ex)
            {

SqlSugerHelper

注：sqlmap部分 没有需要的可以直接删掉

sqlSuger DataTable 转换为自定义 类型集合

注： 主要解决 直接使用sqlquery 出现返回数据首行出现无字段信息问题 

public T ComplexSqlQueryable<T>(string sql) where T : class, new()
        {
            var dt = Queryable(sql);
            var tt = new System.Data.DataTable(typeof(T).Name);
            Type tp = typeof(T);
            //泛型Nullable判断，取其中的类型
            if (tp.IsGenericType)
            {
                tp = tp.GetGenericArguments()[];
            }
            foreach (DataColumn col in dt.Columns)
            {
                BindingFlags flag = BindingFlags.Public | BindingFlags.IgnoreCase | BindingFlags.Instance;
                var type = tp.GetProperty(col.ColumnName, flag);
                var typeres = type == null ? col.DataType : type.PropertyType;
                tt.Columns.Add(new System.Data.DataColumn(col.ColumnName, typeres));
            }
            ; i < dt.Rows.Count; i++)
            {
                System.Data.DataRow dr = tt.NewRow();
                foreach (DataColumn col in dt.Columns)
                {
                    var type = col.DataType;
                    var toType = tt.Columns[col.ColumnName].DataType;
                    if (type != toType)
                    {
                        //文本类型不转换
                        if (toType == typeof(string))
                        {
                            dr[col.ColumnName] = dt.Rows[i][col.ColumnName].ToString();
                            continue;
                        }
                        //空值 取字段默认实例
                        if (string.IsNullOrEmpty(dt.Rows[i][col.ColumnName].ToString()))
                        {
                            dr[col.ColumnName] = Activator.CreateInstance(toType);
                            continue;
                        }
                        var TryParse = toType.GetMethod("TryParse", BindingFlags.Public | BindingFlags.Static, Type.DefaultBinder,
                            new Type[] { typeof(string), toType.MakeByRefType() },
                            ) });
                        var parameters = new object[] { dt.Rows[i][col.ColumnName].ToString(), Activator.CreateInstance(toType) };
                        bool success = (bool)TryParse.Invoke(null, parameters);
                        if (success)
                        {
                            dr[col.ColumnName] = parameters[];
                        }
                    }
                    else
                        dr[col.ColumnName] = dt.Rows[i][col.ColumnName];
                }
                tt.Rows.Add(dr);
            }

            return tt.ToT<T>();
        }

转换方法

其中  获取datatable 方法代码为： 

public DataTable Queryable(string sql)
        {
            return SugerClient.GetInstance().Ado.GetDataTable(sql);
        }

简单转换方法为： 

public static class Extend
    {
        public static List<TT> ToT<TT>(this IEnumerable objs)
        {
            return JsonConvert.DeserializeObject<List<TT>>(JsonConvert.SerializeObject(objs));
        }
        public static TT ToT<TT>(this object obj)
        {
            return JsonConvert.DeserializeObject<TT>(JsonConvert.SerializeObject(obj));
        }
    }

类型转换扩展方法

另转载一个 泛型反射类型转换方法 

public static T ConvertType<T>(object val)
        {
            if (val == null) return default(T);//返回类型的默认值
            Type tp = typeof(T);
            //泛型Nullable判断，取其中的类型
            if (tp.IsGenericType)
            {
                tp = tp.GetGenericArguments()[];
            }
            //string直接返回转换
            if (tp.Name.ToLower() == "string")
            {
                return (T)val;
            }
            //反射获取TryParse方法
            var TryParse = tp.GetMethod("TryParse", BindingFlags.Public | BindingFlags.Static, Type.DefaultBinder,
                new Type[] { typeof(string), tp.MakeByRefType() },
                ) });
            var parameters = new object[] { val, Activator.CreateInstance(tp) };
            bool success = (bool)TryParse.Invoke(null, parameters);
            //成功返回转换后的值，否则返回类型的默认值
            if (success)
            {
                ];
            }
            return default(T);
        }
